Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed January 30. 1906. Serial No. 298.599.

To all whom it Imay concern.'

Be it known that I, HARRY COOPERMAN, a citizen of the United States, residing at the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Brushes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, ol which- This invention relates to brushes, my object being to provide a brush of simple and efficient construction whereby the bristles thereof may be held in place.

The invention relates especially to brushes having a long round body portion; and, as generally stated, the invention consistsin providing means whereby bristles may be held in place to form, substantially, a round end for the brush, as will be hereinafter more fully described and claimed.

In the drawings-Figure 1 is aside elevation of a brush embodying my invention. Fig. 2 is a sectional detail, as on the line 2 2 of Fig. 3. Fig. 3 is a detail of the right hand end of the brush, as seen from the side opposite to that shown in Fig. 1. Fig. 4 is a perspective view ot' the U-shaped piece of metal from which the tube is formed.

1 designates an elongated core and 3 bristles extending therefrom and forming a round brush body. Surrounding one end ol the core 1 adjacent to the end of the round brush body 3 is a tube 4 having an opening 5 in the side wall thereof.

Extending out through one end of the tube 4 is a bunch of bristles 6 forming the end oi the brush, and extending out through the opening 5 are bristles 7 which are so arranged that their outer ends extend from the end of the brush body 3 to the outer end of the bunch of bristles 6, or substantially so, thereby Aforming a brush having a long body portion and a rounded end.

The bristles 6 and 7 are secured to the core 1 and are held in place by the tube 1. The bristles 7 are .divided into two parts, and the parts are arranged on the respective sides of the brush, as shown. One-half ol' themass of bristles 7 on each side of the brush extends from between-the inner wall ol the tube 4 and the outer face of the core 1 on one side of the opening 5, and the other half of the mass of bristles on each side of the brush extends l'rom between the inner wall o'lE the tube 1 and the outer face of the core 1 on the other side of the opening 5. This method of holding4 the bristles 7 in place causes the mass of bristles on each side of the brush to Ilare outwardly and assume spiral-like forms, and thereby substantially connect the brush body 3 with the end bunch of bristles 6.

In the present embodiment of my invention, the core 1 is made of two twisted wires between which the bristles of the brush are securely held, this means of securing the bristles being common and well known in this art.

In constructing a brush in accordance with my invention I, preferably, make the tube from a piece of sheet metal and iirst bend it into U-shaped forni as shown in Fig. l. The U-shaped form is then applied to the core 1 and bristles 6 and 7, and the edges of said form bent to meet and overlap each other to form the tube 4.

1. In a brush., a core, a tube having an opening in the side wall thereof, bristles projecting through said opening and from between the inner wall of the tube and the outer face ol the core, on one side of said opening; and bristles projecting through said opening and from between the inner wall ofthe tube and the outer face ofthe core on the other side of said opening, whereby the mass ol bristles is caused to assume a Haring, spiral-like form, substantially as described.

2. In a brush, a core, a tube having an opening in the side wall thereof, bristles projecting through said opening and fromy between the inner wall of the tube and the outer face of the core, on one side of said opening; bristles projecting through said opening and from between the inner wall of the tube and the outer face oi the core on the other side of said opening, whereby the mass of bristles is caused to assume a flaring, spiral-like form, and a bunch of bristles extending out through one end of the tube, substantially as described.

In testimony whereof, I have hereunto a'l'lixed my signature.
